What this current-feedback amp brings to the bench
The ADEL2020AR is a single-channel current-feedback operational amplifier from Analog Devices, built for applications that need fast slew rates and wide bandwidth without the gain-bandwidth trade-off of voltage-feedback amps. The supply range spans 6 V to 36 V, so you can run it from a single +12 V rail or split ±5 V / ±15 V supplies — common on mixed-signal boards that already carry ±15 V for analog front ends. The 6.8 mA quiescent current per amplifier is moderate; it won't starve a portable design, but it's not a micropower part either.
At 500 V/µs, this amplifier can swing a 5 V peak-to-peak signal in 10 ns — fast enough for composite video (NTSC/PAL), radar IF pulses, or high-speed data converter inputs without slew-induced distortion. The 90 MHz -3 dB bandwidth is the small-signal limit; with current-feedback topology, bandwidth stays nearly constant as you increase closed-loop gain, unlike voltage-feedback amps where gain and bandwidth trade off directly.
Package and mounting for the layout engineer
The supplier device package is 20-SOIC. This is a standard footprint shared by many high-speed op-amps and interface ICs, so PCB layout reuse across designs is straightforward. The listed shipping form is Bulk — tubes or trays, not tape-and-reel — something to note if your pick-and-place line expects reeled parts.
